Siarnaq, Moon of Saturn

Siarnaq is a Moon that orbits round Saturn rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 108,394,044.13 km. The furthest it gets from its orbital parent (apoasis) is 25,315,240 km. Its mass is estimated/calculated at being 38,965,379,260,527,000 kg. Its density has been calculated at being 2.3 g/cm3. Its volume is 2.3 g/cm3. It was discovered on 23 September 2000 by Brett J. Gladman, John J. Kavelaars, Jean-Marc Petit, Hans Scholl, Matthew J. Holman, Brian G. Marsd.

The Semi-Major Axis of the orbit is 18,015,400 km, which is the furthest point from the centre to the edge of an elliptical point.

The mass of the object is calculated at being 38,965,379,260,527,000 kg. The equatorial circumference of Siarnaq is 125.7 km. The mean radius of Siarnaq is 20.0 (assuming an albedo of 0.06) km. The surface area of Siarnaq is 5,026.55 km2. The surface gravity of the said item is 0.007 m/s2. The average orbit velocity, that is the speed at which it orbits is 5,038.2 km/h.

The orbital inclination, the angle at which Siarnaq orbits in relation to the orbital plane is 44.507 degrees. The orbital eccentricity is 0.4052, it is the degree at which Siarnaq orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
